问题描述
这是我的code：

<head>
<body>
<?php
require_once 'facebook-php-sdk/src/facebook.php';
$appapikey = '453976824647366';
$appsecret = 'fe86f3b0b34b3ed6eb39bbce717b8062';
$facebook = new Facebook($appapikey, $appsecret);

推荐答案
要检查的第一件事是
require_once 'facebook-php-sdk/src/facebook.php';
请确保它是相对于您的PHP code为，而不是服务器结构。
Make sure it is relative to where your php code is rather than to the server structure.
要测试这个code，我可能只是使用被Facebook SDK提供的现有的例子，这样你得到它的第一次合作，通过自信地知道它真正的作品，然后就可以调整它按您的需要。
正是从这个链接粘贴
https://github.com/facebook/facebook-php -sdk / BLOB /主/例子/使用example.php
To test this code I would probably just use the existing example provided by Facebook sdk, that way you get it working first by confidently knowing that it really works and can then tweak it as per your needed. Just pasting it from this link https://github.com/facebook/facebook-php-sdk/blob/master/examples/example.php
